• What is the cause and solution for SAP error message RSDME782 - Source &2 of Model &1 is not attached to BW DataSource ?

  The SAP error message RSDME782 indicates that a source object (like a DataSource) is not properly attached to a BW model. This typically occurs in the context of SAP BW (Business Warehouse) when you are trying to use a model that references a DataSource that has not been linked correctly.
  Cause:
  
  Missing Attachment: The DataSource specified in the error message is not attached to the BW model. This can happen if the DataSource was deleted, not activated, or not properly linked during the modeling process.
  Incorrect Configuration: There may be configuration issues in the BW model or the DataSource itself that prevent them from being linked.
  Transport Issues: If the model or DataSource was transported from one system to another, the attachment might not have been included in the transport.
  
  Solution:
  
  
  Check DataSource Attachment:
  
  Go to the BW model in the SAP BW modeling tools.
  Verify if the DataSource is attached to the model. If it is not, you will need to attach it.
  You can do this by editing the model and adding the DataSource from the available options.
  
  
  
  Activate the DataSource:
  
  Ensure that the DataSource is activated. You can check this in the DataSource maintenance transaction (e.g., RSA1).
  If it is not activated, activate it and then try to access the model again.
  
  
  
  Recreate the Link:
  
  If the DataSource is present but not linked correctly, you may need to remove it and then re-add it to the model.
  
  
  
  Check for Transport Issues:
  
  If the model or DataSource was recently transported, check the transport logs to ensure that all necessary objects were included in the transport.
  If something is missing, you may need to transport the missing objects again.
  
  
  
  Review Documentation:
  
  Consult the SAP documentation or help resources for any specific requirements or steps related to your version of SAP BW.
  
  
  
  Related Information:
